Definitions

  • the present invention relates generally to the field of transport and / or storage of a radioactive medium generating by radiolysis flammable and / or explosive gases, such as hydrogen.
  • such a radioactive medium is usually placed in an interior storage space defined by a bottle.
  • a radioactive medium When several bottles are filled and closed by plugs, they are then arranged on a bottle holder and inserted into a cavity defined by a package.
  • the set obtained, called transport package and / or storage of a radioactive medium may for example include ten bottles distributed on the bottle carrier.
  • radioactive liquid medium which usually comprises plutonium
  • it is likely to generate by radiolysis flammable and / or explosive gases, such as hydrogen.
  • the radioactive medium whether it is a liquid in which the radioactive material is in ionic form and / or in the form of solid particles dispersed in the liquid, constitutes an ⁇ -particle emitter which has in particular the particularity of dissociating the hydrogenated molecules, to release flammable gaseous compounds.
  • the radiolysed molecules may be part of the medium, and / or the constituent material of the canister.
  • the flammable gases produced by radiolysis constitute, in the presence of other gases such as air, an explosive mixture.
  • the flammability threshold varies according to the nature of the gas flammable and according to the conditions of temperature and pressure. In the particular case of hydrogen, the flammability threshold in the air is around 4%. This means that when the hydrogen concentration in the air exceeds this threshold, a source of heat or a spark can be enough to ignite the mixture or to produce a violent explosion in the internal storage space, the latter being indeed only partially filled by the radioactive medium, and supplemented by a gaseous sky.
  • Another solution could be to keep the same volume of radioactive medium in the bottle, but by enlarging the internal storage space so as to increase the volume of the gas. Nevertheless, this leads to the manufacture of very large bottles, which makes their exploitation difficult, especially during the loading phases of the radioactive medium in the canister, which is generally carried out in a glove box.
  • the invention therefore aims to at least partially overcome the disadvantages mentioned above, relating to the achievements of the prior art.
  • the invention firstly relates to a packaging device for transporting and / or storing a radioactive medium generating by radiolysis of flammable and / or explosive gases, said device comprising at least one bottle for contain the radioactive medium, said bottle defining an internal storage space accessible through a filling opening of the medium, on which are mounted plug means.
  • said device also comprises an enclosure structure, as well as communication means for establishing a first fluid communication between said internal storage space and said enclosure.
  • the flammable and / or explosive gases produced by radiolysis during the storage and / or transport of the radioactive medium can spread not only in the unfilled part of the interior storage space of the canister, called gaseous sky, but also in the volume of the enclosure through the presence of said first fluid communication. Since the gases generated by radiolysis can be diluted in a larger volume than that of the simple gas sky of the canister, each can can therefore contain a larger amount of radioactive medium, without risking to reach the threshold of flammability of these gas. This increase in the filling rate of the canisters implies a significant economic gain, since for a given amount of medium, it reduces the number of transports to be performed.
  • the invention also makes it possible to increase the duration of transport / storage, without risking to reach the flammability threshold of the gases generated by radiolysis, always because these gases can be diluted in a larger volume.
  • each bottle can remain small in size, favoring easier operation, particularly with regard to the operation of filling of the medium in the internal storage space, which is usually done in a glove box. It is only after the filling and the installation of the cap means that the internal storage space and the enclosure are put into fluid communication.
  • each bottle is preferably designed to be arranged outside the chamber, preferably being removably mounted on the structure, it is possible to provide an embodiment in which each bottle is housed in the enclosure with which its internal storage space communicates. Also, in the case where the canisters are arranged outside the enclosure, they can alternatively be placed at a distance from the enclosure structure without being mounted mechanically thereon.
  • the invention applies to the conditioning of radioactive liquid media, but also to the packaging of all other radioactive media capable of generating, by radiolysis, flammable and / or explosive gases.
  • the bottle further comprises a first orifice opening into the internal storage space, said enclosure structure comprises a second orifice opening into said enclosure, and said first and second ports constitute the two opposite ends of said first fluid communication.
  • This first embodiment corresponds to a case where the bottle is intended to be arranged outside the enclosure, being preferably removably mounted on the structure.
  • Said first fluid communication can integrate any element between the first and second orifices, in particular controllable means alternatively for releasing / closing these first and second orifices.

  • the actuator can be manually controlled by an operator, or be set in motion automatically, in response to an operator-activated signal.
  • the bottle further comprises a third orifice opening into the internal storage space
  • said enclosure structure comprises a fourth orifice opening into said enclosure
  • said communicating means makes it possible to establish a second fluid communication between said internal storage space and said enclosure, said third and fourth orifices constituting the two opposite ends of said second fluid communication.
  • the flammable and / or explosive gases produced by radiolysis during the storage and / or transport of the radioactive medium can spread in the volume of the enclosure by borrowing both said first fluid communication and said second fluid communication.
  • a number of fluidic communications greater than two could be provided between the chamber and the interior storage space of the canopy, without departing from the scope of the invention.

  • the actuating member is designed such that its displacement from its closed position to its open position, with said canister resting on this first movable member, ensures a mechanical connection of the canopy, and so that the moving from its open position to its closed position ensures a mechanical disconnection of this bottle. Therefore, a single action on this actuator can generate simultaneously effects on the mechanical connection, as well as effects on fluid communication.
